Rail container delays spike at LA-LB ports amid record volumes

Rail-destined container dwell times at the Los Angeles-Long Beach port complex reached 6.75 days in August, the highest level in the past year, even as truck-based cargo continued moving smoothly at 2.95 days. This divergence reveals a critical bottleneck in intermodal logistics: while marine terminals and drayage operations successfully managed near-record volumes of 1.88 million TEUs, Class I rail carriers (Union Pacific and BNSF) struggled to clear inland-bound containers at their historical pace. The growing gap between truck and rail dwell times signals that inland rail capacity, particularly on-dock and near-dock terminal operations, cannot keep pace with sustained import flows destined for Midwest and Southern U.S. distribution centers.

This constraint becomes especially relevant given ongoing industry debates about rail network consolidation and competitive capacity. Supply chain teams relying on rail intermodal should expect longer container holding periods and plan inventory and appointment strategies accordingly. As the fall shipping season approaches, this metric will become increasingly important.

Shippers moving goods through LA-LB cannot assume that strong truck-side performance guarantees smooth end-to-end transit. Rail bottlenecks upstream will compress overall supply chain velocity, potentially extending lead times for inland delivery despite strong port performance on the truck side.
